BRI1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0189950, also known as BRI1 or HvRLCK156, encodes a transmembrane receptor serine/threonine kinase with protein kinase activity, steroid binding, and sugar binding functions. This barley gene on chromosome 2H is associated with brassinosteroid-mediated signalling, detection of brassinosteroid stimulus, skotomorphogenesis, regulation of stomatal complex development, and embryo sac development. It has been connected to grain size, grain weight, and leaf angle traits. The gene product localises to the plasma membrane, endosome, and extracellular regions. Studies of related genes in other species link the family to plant height, grain yield, drought tolerance, root length, and chlorophyll content.
